The Power of R: More Companies Using Language for Business Analytics - Page 2 | Intervi... - 0 views

  • Part of what we are doing is helping to consumerize or democratize analytics. Because we can provide this software so much more cost effectively, it's giving opportunities for individuals, startups, small and medium businesses to come in and have equal analytic capability and processing power both from a software standpoint, but also from the more cost-effective hardware that we're able to run on to give them the same tools that these giant organizations do. So now all of a sudden we've started to level the playing field a little bit.

  • R is particularly useful because it contains a number of built-in mechanisms for organizing data, running calculations on the information and creating graphical representations of data sets.
  • What makes R so useful
  • is that statisticians, engineers and scientists can improve the software’s code or write variations for specific tasks. Packages written for R add advanced algorithms, colored and textured graphs and mining techniques to dig deeper into databases.

      En esta entrevista al director de operaciones de Revolution Analytics, Jeff Edhardt, se explica brevemente lo que es el lenguaje R, un lenguaje de programación estadístico de código abierto, usado para analizar cualquier tipo de dato. Remarca el hecho de que se está extendiendo cada vez más ya que las compañías que utilizan alguna herramienta de análisis de datos están obteniendo un mayor rendimiento en la empresa. Jeff Edhardt finaliza explicando el amplio rango de aplicaciones que se le pueden extraer a este lenguaje.
  • It's incredibly diverse. It ranges from pharmaceuticals for drug developments, biostatistics, gene analysis, genetic analysis into finance. It's very heavily used in hedge funds, quantitative finance risk, credit analysis, fraud detection, understanding customer churn, understanding customer behavior, pricing optimization forecasting. We have customers who are entertainment or gaming companies using it to understand buying patterns and effectiveness of different media campaigns. So it ranges anywhere from life sciences to finance to Internet to telecom.

Revolution Analytics Rides R Language into Mainstream Business | - 0 views

    • diigo lemon
       
      Revolution Analytics es un proveedor comercial de software y servicios relacionados con el lenguaje R. Es un lenguaje de programación basado en estadística que tiene muchos usuarios. Las empresas están recogiendo enormes cantidades de datos, pero a menudo no pueden analizar los mismos debido a problemas de escala. Revolution Analytics ayuda a afrontar estos problemas mediante un nuevo enfoque. "Revolution R" proporciona velocidad y escala en el análisis de grandes datos.
  • Revolution Analytics provides value by taking the most recent release from the R community and adding scalability and other functionality so that R can be implemented and seamlessly work in a commercial environment. Revolution R provides a development environment so that data scientists can write and debug R code more effectively, and web service APIs that integrate with other BI tools and dashboards so that R can work with business intelligence tools and visual discovery tools. In addition, Revolution Analytics makes money through professional and support services.

      Miestra como una empresa puede ofrecer un servicio basado en R como producto.
  • For example, IBM’s PureData System for Analytics (IBM’s new name for its MPP Netezza appliance) uses the in-database approach with an R instance running on each processing unit in the database, each of which is connected to an R server via ODBC. The analytics are invoked as the data is served up to the processor such that the algorithms run in parallel across all of the data.

  • I’ve heard that Revolution R isn’t always the easiest software to use and that the experience isn’t exactly seamless, but it can be argued that in the cutting-edge field of big data analytics a challenging environment is to be expected. If Revolution Analytics can address some of these useability challenges, it may find its pie growing even faster than it is now. Regardless, I anticipate that Revolution Analytics will continue its fast growth (already its headcount is doubling year-over-year). Furthermore, I anticipate that in-database analytics (an area where R really shines) will become the de-facto approach to big data analytics and that companies that take full advantage of that trend will reap benefits.

Actuarial Analytics in R - 0 views

      En este artículo se expone la increible versatilidad del lenguaje R con un monton de ejemplos en los que se ha usado (Analisis de estadisticas en Baseball, juzgar la calidad de un vino, analisis de datos de un scanner de supermercado) y luego introduce una presentacion donde se analizan 4 casos entre los que se encuentra uno interesante sobre el tiempo ademas de otro donde se valora los datos de un grupo de trabajadores
  • With data analysis showing up in domains as varied as baseball, evidence-based medicine, predicting recidivism and child support lapses, judging wine quality, credit scoring, supermarket scanner data analysis, and “genius” recommendation engines, “business analytics” is part of the zeitgeist. This is a good moment for actuaries to remember that their discipline is arguably the first – and a quarter of a millennium old – example of business analytics at work.
  • This session will include an overview of the R statistical computing environment as well as a sequence of brief case studies of actuarial analyses in R. Case studies will include examples from loss distribution analysis, ratemaking, loss reserving, and predictive modeling.
